Skylla-TG 24/50(1+1) 3-Phase 400V - Battery charger 24V 50A
Skylla-TG 24/50(1+1) 3-Phase 400V is a 24 V battery charger with a nominal charge current of 50 A, supplied from a three-phase 3 x 400 V network. It has a main output and a 4 A output for a starter battery, a three-stage IUoU algorithm and an included temperature sensor. It is intended for three-phase installations and battery banks of 250-500 Ah.
Main features:
- Battery voltage: 24 V
- Charge current: 50 A
- AC input: 3 x 400 V (320-450 V)
- Charge outputs: 1 main + 1 × 4 A (starter)
- Charge algorithm: IUoU, three-stage
- Recommended capacity: 250-500 Ah
One full rated output and one 4 Amp output. Charge voltage can be precisely adjusted to suit any battery system. The input for the charger is 230V at 50/60HZ. Charge voltage can be measured directly on the battery terminals in order to compensate for voltage loss due to cable resistance. An external sensor allows measuring battery temperature and compensating charge voltage accordingly.
